RESUMEN
BACKGROUND: The aim of the study was to identify the variables of the internal compensatory mechanisms that differentiate the body build and posture of people with Down syndrome (DS) from the intellectual disability (ID) population. It was assumed that gaining knowledge in the abovementioned aspect will allow for a better understanding of the limitation of the kinesthetic abilities of people with ID and DS and simultaneously enable to optimize the process of planning and interventions to improve physical activity in this population with the adequate use of theirs strengths in the biomechanical and morphofunctional systems. METHODS: The methodology of this systematic review was developed according to the PRISMA guidelines. A search of PubMed, EBSCO, Scopus databases was conducted to identify all studies on DS/ID and the body build and posture from 2003 to 2023. RESULTS: 395 articles were assessed to determine eligibility, while 22 studies met the inclusion criteria and were subjected to detailed analysis and assessment of their methodological quality. The differentiation of the body build and posture in DS population can be induced by both internal and external compensatory mechanisms. It is difficult to confirm the direct effect of the intrinsic variables that impact the body build and posture in the ID population, excluding people with DS. CONCLUSIONS: Compared to other ID, the intrinsic differences in the body build and posture in DS individuals were induced by gender, age, and level of ID. The tendency for diversity between DS and other ID populations in body build and posture may be determined by the presence of the third copy of chromosome 21 in DS group. Internal compensatory processes may be induced mainly by abnormalities in the structure of the cervical vertebrae and feet. IQ should not be used as the only variable that identifies the population of people with ID.

BACKGROUND: The BMI index cannot always be used in people with intellectual disabilities due to neuromuscular coordination disorders and psychological barriers that may hinder conventional body weight measurement. The study aimed to assess the usefulness of BMI and BAI in estimating obesity and body fat in people with intellectual disabilities. METHODS: The first stage of the research involved 161 people with profound intellectual disabilities. Somatic parameters (BM, BH, WC, HC) were measured and BMI, BAI, WHR were calculated. Fifty seven persons with above-normal BMI and BAI were included in the second stage of the study and biochemical parameters were determined (TC, LDL-cholesterol, HDL-cholesterol, TG, GL). RESULTS: According to both BMI and BAI classifications, most people were overweight or obese. A high correlation of %BF with BMI and BAI indices was observed (r = 0.78). The sensitivity of both indices was 95.65%. In groups with above-normal BMI and BAI, an upward trend was found for mean values of TC, LDL, TG, and GL, with a simultaneous downward trend for HDL. Statistically significant intergroup differences were recorded for TG and GL (p < 0.05) for both indices (BMI and BAI). CONCLUSIONS: Our research demonstrated that BAI is complementary to BMI and can be recommended for the estimation of body fat and cardiometabolic risks in people with intellectual disabilities. Due to the ease of measurement, BAI has high utility value.

INTRODUCTION: This study assessed overweight, obesity and lipid profiles in adults with intellectual disability and compared these metrics with their physical activity. MATERIALS AND METHOD: Basic somatic parameters, lipid profile and weekly physical activity were examined in 27 adults with moderate intellectual disability. Chi-square independence tests and Pearson's linear correlation coefficients were used. RESULTS: The participants had excess body mass, excess body fat and abdominal obesity. Very high positive correlations were shown between body mass index and both waist circumference and %fat. The lipid profiles were more favourable in the general population. Healthy levels of physical activity were observed in 8% of women and 26% of men. A high negative correlation was found between physical activity and body mass index. CONCLUSION: The study group was characterized by excess body mass and insufficient levels of physical activity. Body mass index and waist circumference are sufficient indicators for identifying obesity in adults with intellectual disability.

Introduction: Although the assessment of physique and body composition poses methodological, technical, and interpretative difficulties, it is of great importance for the health of people with disabilities. The aim of the study was to demonstrate that sedentariness and sports activity are factors differentiating anthropometric characteristics, indices, and body composition in people with physical disabilities. Materials and methods: Fifty-eight people were examined: 48 elite Polish Para athletes, including Paralympic track and field athletes (PTF, n = 8), sitting volleyball players (SV, n = 15), wheelchair rugby players (WR, n = 25), and individuals with cervical spinal cord injury (CSCI, n = 10). Body mass (BM), body height (BH), body length (BL), waist circumference (WC), hip circumference (HC), body fat percentage (%FT), and visceral fat rating (VFR) were measured. Furthermore, BMI, BMIcorrected, and body adiposity index (BAI) were evaluated. Results: The highest WC, BAI, %FT, and VFR were found for the CSCI group. The type of sport significantly differentiated between anthropometric features, indices, and body composition of the athletes. Sitting volleyball players achieved the highest mean BM (83.9), WC (92.9), HC (103.7), BMI (24.5), BAI (23.4), and VFR (12.6). The highest %FT (28.9) was found in wheelchair rugby players. Conclusions: The results of the present study indicate that forced sedentariness and sports activity among individuals with disabilities differentiate body structure and physique.
RESUMEN
BACKGROUND: With the dynamic development of professional Paralympic sport, the prevalence of musculoskeletal pain and structural and/or functional disturbances in Para athletes constantly increases. The aim of the study was to evaluate the impact of internal compensatory mechanisms on selected aspects of body structure and function in elite sitting volleyball players. METHODS: The study included eighteen elite sitting volleyball players (male; n = 12, female; n = 6, age; 36.0 ± 6.1, body mass; 76.6 ± 16.1, body height; 179.3 ± 0.1) from the Polish national team. Retrospective and direct participatory observation methods were used in the study. NMQ-7 was used to assess the current prevalence and location of musculoskeletal pain. The evaluation of spinal curvature and pelvic inclination was performed using a non-invasive Medi Mouse method (Idiag M360) in three different trunk positions. All statistical analyses were performed using Statistica 13.3 software package. RESULTS: Lumbar hypolordosis was a predominant sagittal deviation of spinal curvature (n = 15;83%). Low back pain (LBP) and neck pain were the most frequent complaints (50%). Statistically significant differences in the values of thoracic kyphosis angle, pelvic inclination, and spine length (SL) in sagittal standing flexion and extension were found. However, there was no statistically significant difference in sagittal standing flexion for the lumbar lordosis angle with a simultaneous significant change in pelvic inclination (66.9°). Moreover, a tendency to interpenetration of relationships between variables that characterize (a) body structure and (b) function of the spine and musculoskeletal pain were observed. Shoulder pain correlated with SL (R = 0.6; p < 0.05) and body height (R = 0.5; p < 0.05). Pelvic inclination correlated with shoulder pain, LBP (R = 0.5; p < 0.05/R = 0.6; p < 0.01), and body trunk fat mass (R = - 0.6; p < 0.05). CONCLUSIONS: Trunk fat mass induces internal compensatory mechanisms to maintain optimal pelvic inclination and sagittal spinal balance. Furthermore, the level of pelvic mobility may determine musculoskeletal pain in Para athletes with lower limb impairment.
RESUMEN
The purpose of the study was to evaluate the impact of (1) maximal muscular strength of the upper body and (2) fat mass on musculoskeletal pain and sagittal spinal curvature deviations in elite Polish sitting volleyball players. The study examined twelve players (age = 35.4 ± 6.9 years). The assessments were performed based on objective (anthropometric examinations, Medi Mouse, 1RM test) and subjective (NMQ = 7) measurements. All statistical analyses were performed using the SPSS. The lower back, the upper back and the neck were the most frequent painful areas. Statistical analyses showed a significant relationship between lumbar lordosis (LL) sagittal standing extension (r = 0.62; p = 0.03) and thoracic kyphosis (TK) sagittal standing flexion (r = -0.63; p = 0.28) with the 1RM. Furthermore, correlations between a body adiposity index and TK sagittal standing flexion and extension (r = -0.65; p = 0.05, r = - 0.58; p = 0.0.05) as well as LL sagittal standing flexion (r = 0.61; p = 0.05) were found. The body mass index correlated with wrist pain, whereas a very high relationship was found between pain in the wrists and knee joints. Neck pain positively correlated with TK and LL sagittal standing. Low back pain correlated with LL sagittal standing flexion and TK sagittal standing extension. Fat mass impacts the depth of anteroposterior spinal curvatures, what may cause pain in the neck and the lower back. The 1 RM bench press may influence the prevalence and location of musculoskeletal pain, whereas its values might be predicted by the depth of TK. A lower 1RM in the bench press may impact sagittal spinal curvature deviations. Deepen TK and LL significantly contribute to the prevalence of the neck pain.
RESUMEN
The purpose of the present study was to examine the acute effects of the bench press exercise with predetermined velocity loss percentage on subsequent bench press throw (BPT) performance with raised legs or feet on the floor among disabled, sitting volleyball players. Twelve elite sitting volleyball athletes (age = 33 ± 9 years; body mass = 84.7 ± 14.7 kg; relative bench press maximum strength = 1.0 ± 0.3 kg/body mass) took part in this study. The experiment was performed following a randomized crossover design, where each participant performed a single set of bench press with a 60% one-repetition maximum (1RM) to a 10% decrease of mean bar velocity as a conditioning activity (CA). The BPT with a 60%1RM was performed to assess changes in peak power (PP), peak velocity (PV) before and after the CA. The differences between analyzed variables before and after the CA were verified using two-way repeated-measures ANOVA (condition × time; 2 × 2). The ANOVA showed a significant main effect of time for peak bar velocity (p = 0.03; η2 = 0.312) and peak power output (p = 0.037; η2 = 0.294). The post hoc comparison showed a significant increase in post-CA peak bar velocity and peak power for raised legs condition in comparison with pre-CA value (p = 0.02, p = 0.041, respectively). The present study showed that the subsequent BPT performed with raised legs could be enhanced by the bench press with a 60% 1RM to a 10% mean bar velocity decrease as a CA among disabled sitting volleyball players. Therefore, athletes and coaches can consider performing a bench press throw with raised legs without compromising performance.

BACKGROUND: The last decade has seen the dynamic development of Paralympic sport, including the development of training facilities and training methods that allow for the achievement of results at the highest level in this group. This may be associated with an increased risk of injury and traumas. This study aimed to evaluate the prevalence and locations of injuries and the types of trauma suffered by goalball players. METHODS: The study covered 43 players (24 women and 19 men) of the Goalball European Championship. A questionnaire survey was conducted. RESULTS: The injuries were reported by 44%. Most often they concerned the upper limbs (92%). Positive correlations were found between age and prevalence of pelvis and knee joint injuries, whereas negative correlations occurred between competitive experience and the prevalence and location of injuries in the area of the upper limb. The highest percentage of trauma was found for epidermal abrasions, contusions, and dislocations. A negative correlation was observed between age and the prevalence of epidermal abrasions, whereas a positive correlation occurred between age and the prevalence of sprains and dislocations. The competitive experience was negatively correlated with the prevalence of abrasions and contusions and positively correlated with the prevalence of sprains and dislocations. A statistically significant correlation was found between body mass (BM) and the prevalence of injuries. In 23% of cases, training was interrupted for more than one month, whereas in 43%, the break was below one month. CONCLUSIONS: Playing position in goalball does not affect the prevalence of injuries and traumas, while body mass has a moderate effect on the prevalence of these events. The age of the subjects and their sports experience impact significantly on the prevalence and types of injuries.

INTRODUCTION: Physical fitness is a resultant of the efficiency of adaptive mechanisms for physical effort. People with intellectual disabilities may exhibit limited adaptive capacities, not only regarding their mental development, but also physiological, social and emotional development. Dysfunctions of the central nervous system observed in individuals with intellectual disabilities cause difficulties in gaining movement experience as well as problems with coordination and kinesthetic sense. Thus, intellectual disability might cause low physical activity and, consequently, low physical fitness. OBJECTIVE: The aim of the present investigations was to evaluate aerobic capacity of intellectually disabled adults and determine its potential relationships with the degree of intellectual disability, somatic parameters, age and gender. MATERIALS AND METHOD: The study group consisted of 85 intellectually disabled adults aged 20 to 40 years. The investigations were based on direct observation of the participants. The following somatic parameters were measured: body height and weight, waist and hip circumference, body fat percentage, body mass index and waist-to-hip ratio. Physical fitness was evaluated based on PWC170; VO2max was also calculated. Qualitative assessment of physical fitness level was carried out using Astrand's classification (with respect to age and gender). RESULTS: 30% of women and 46.3% of men had very low level of aerobic capacity. Absolute values of PWC170 and VO2max were significantly higher in men. However, relative values expressed in millilitres of oxygen per kilogram of body weight did not reveal statistically significant inter-gender differences. Age and degree of intellectual disability did not significantly influence the level of physical fitness. Multiple regression analysis to estimate VO2max/kg revealed a negative correlation with %FAT and WHR. CONCLUSIONS: 1. A large sample of the study population (30% female, 46,3% male) showed very low levels of aerobic capacity. 2. Our investigations did not demonstrate a relationship between physical fitness and age or the degree of intellectual disability. Gender turned out to be a differentiating factor but only for the absolute PWC170 and VO2max. 3. The level of physical fitness was significantly related to somatic parameters including body mass, waist and hips circumference, percentage of body fat, BMI and WHR.
